Micron has stopped making the specific 2GB GDDR7 memory chips that power NVIDIA's GeForce RTX 50 series graphics cards. This shift removes one of the three original suppliers from the market, leaving Samsung and SK hynix as the sole providers for these components. Buyers relying on RTX 50 desktop and mobile GPUs now face a consolidated supply chain with no alternative source for Micron-sourced memory modules. We track these component changes closely because they directly impact the availability and potential cost of next-generation gaming hardware.
Samsung and SK hynix become sole suppliers
The company officially listed its two primary GDDR7 part numbers as End of Life. These specific chips, identified as MT68A512M32DF-28:A running at 28 Gbps and MT68A512M32DF-32:A running at 32 Gbps, are no longer in production. Micron originally entered the GDDR7 supply chain in mid-2025, with its memory first appearing on RTX 50 mobile GPUs by February. The halt in manufacturing marks a significant contraction in the early GDDR7 ecosystem, which was initially supported by three major memory manufacturers.
- Part Number (28 Gbps): MT68A512M32DF-28:A
- Part Number (32 Gbps): MT68A512M32DF-32:A
- Status: End of Life
- Density: 2GB
Despite ending 2GB production, Micron continues to manufacture 3GB GDDR7 modules. These higher-density parts are currently priced above standard 2GB chips and have been reported as largely unworkable for most of the current RTX 50 stack. NVIDIA and its partners have not widely adopted these 3GB variants, leaving them as a technical dead end for current hardware. The company is also expected to release higher-density 4GB and 6GB GDDR7 chips, but those products are likely at least two years away from availability.
The exit of Micron from the 2GB segment should not trigger an immediate dramatic supply collapse. Micron was never the primary source for these memory modules, and the remaining suppliers can absorb the demand. We have been tracking GDDR7 Memory closely and previously covered Samsung's potential to enable massive workstation GPUs with its own GDDR7 innovations. This consolidation simplifies the supply chain but reduces competition among memory vendors for the RTX 50 series.
Micron's decision to halt 2GB GDDR7 production leaves Samsung and SK hynix as the exclusive suppliers for this specific memory configuration. The 3GB modules remain in production but offer no practical benefit for current RTX 50 hardware. Higher density options are still years away, leaving the market dependent on the two remaining vendors for the foreseeable future.
